BOX-BASE FOR RADIATORS.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed November 17, 1906. Serial No. 343,808.

To all LU/b07711 it may concern:

Be it known that I, MONTGOMERY E. DAN- FORTH, a citizen of the United States, residing at WVashington, in the District of Co lumbia, have invented new and useful Improvements in Box-Bases for Radiators, of which the'following is a specification.

My invention relates to box bases for radiators, and has for its object to provide certain improvements in the details of cons truction of the same as will be hereinafter more definitely pointed out and claimed, reference being had to the accompanying drawing, in which:

Figure 1 is a perspective view of a radiator having my improved box base located in position with respect thereto. Fig. 2 is a top plan view of the box base, the front and back wall plates being shown in section. Fig. 3 is a vertical transverse sectional view of a portion of a radiator and the box base. Fig. at is a detail elevation of one end of the box base removed from the radiator.

Similar numerals of reference denote corresponding parts in the several views.

In the said drawing the reference numerals 1 denote the end walls of the box base, the device being open at top and bottom, and being adapted to fill the space beneath the radiator 2, with respect to which it is removably located. The front wall of said box base consists of a plate 3, apertured at 4 for the admission of air, and detachably attached to said end walls 1 by means of screws 5 engaging ears 6 formed on said end walls 1. Similarly, the back wall plate is attached to said end walls 1, said back wall plate being also apertured at 8 and being pro vided with an extension flange 9 aroundsaid aperture, which, when said box base is located in position, projects into and fits in a pipe 10 that extends through the wall 11 of the building to the open air.

Mounted centrally and longitudinally within the box base is a shaft 12, having fixed thereon to oscillate therewith one or more wings 13 projecting on both sides of said shaft to span the transverse area of the box base, the same, when in their normal horizontal position, shown in Figs. 2 and 3, con tacting with dampers 14 closing the openings 4 and 8 in the front and rear wall plates 3 and 7, said dampers being pivoted at their bottoms upon ears 15 projecting from the body 1 of the box base. Near one end the shaft 12 is provided with a rock arm 16, to which is connected an operating rod 17 that projects through an aperture 18 in the front wall plate 3, and is provided at its outer end with a removable handle 19, said rod being also notched at 20 to engage the front wall plate 3 to retain said rod and its connected parts in the position shown in Fig. 3.

From the above description the operation of my improved construction will be understood as follows: With the operating rod 17, shaft 12, and wings 13 in the position shown in full lines in Fig. 3, the ends of said wings by their contact with the dampers 14 will maintain both of the latter in their closed position, so that no air at all will be admitted to the base of the radiator. N 0w, when it is desired to have a circulation of the air within the room upwardly through the radiator, the rod 17 is pushed inward, thereby, through rock arm 16, turning shaft 12 and wings 13 to the position shown in dotted lines in Fig. 3, the result being that, while the rear damper 1 1 is still contacted with by said wings to retain it closed, the front ends of said wings will drop below and away from contact with the front damper, as shown, and, as the latter is so pivoted that it will fall inward. by gravity when released, it follows that said damper will instantly open to the position shown in dotted lines in Fig. 3, thereby admitting the air of the room to the box base. To admit air from the outside, through pipe 10, the movement of rod 17 is reversed, the same being pulled out, which rocks the wings 13 in the opposite direction, thus closing the front damper and permitting the rear damper covering opening 8 to fall open by gravity.

It will be observed that the ends 21 of the wings 13 where they contact with the dampers 1 1 are curved on the arc of a circle struck from the shaft 12 to permit a free sliding movement of said wings against the dampers 14, and at the same time, when. in contact therewith, maintaining said dam ers completely closed. From this it will be c ear that, while either the front or the rear damper may be opened, they cannot both be opened at the same time, and so long as one of them is open, even in the slightest degree,

so that air cannot pass either inward or out ward through pipe 10 without passingthrough the radiator 2.

While I have shown, and prefer to use, two wings 13, one at each end of the dampers 14, it will be understood that I may employ but a single wing centrally located with respect to saiddarnpers, or may employ three or' morewings, according to the length of the dampers.

By forming the front wall plate 3 separatefrom the body of the box base I am enabled, by removing said front plate, to gain access to theinterior of the box base for cleaning purposes without removing said box base as a whole.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a box base for radiators having an air inlet in each side, dampers for said air inlets, and means for retaining both of. said dampers closed or for permitting either of saiddampers at a time to be opened.

2. In a box base for radiators having an air inlet in each side, dampers for said air in lets, and a common means for retaining both of said dampers closed or for permitting either of said dampers at a time to be opened. I 3. In a box base for radiators having an air inlet in each side, dampers for said air inlets opening by gravity, and means for retainingboth of said" dampers closed or for permitting either of said dampers at a time to-be opened.

4. In a box base for radiators having an air inlet in each side, dampers for said air in lets opening by gravity, a wing spanning the space between saiddampers to retain them both closed, and meansfor moving said wing to release either of said dampers while retaining the other damper closed.

5. In a box base for radiators having an air inlet in each side, dampers for said air in lets opening by gravity, a wing pivoted intermediate its length and spannin'gthe space between said dampers to retain them both closed, and means for rocking said; wing on its pivot to release either of said dampers while retaining the other damper closed.

6; In a box base for radiators having an air inlet in each side, dampers for said air in lets opening by gravity, a shaft mounted in said box base,'a wing fixed intermediate its length upon said shaft and spanning the space between said dampers to retain them both closed, and means for rocking said shaft and wing to release either of said dampers while retaining-the other damper closed.v

7. In a box base for radiators having an air inlet in each side, dampers for said air inlets opening by gravity, a shaft mounted in said box base, a wingfixed-intermediate -its length upon said shaft. andv spanning the space'between said dampers to retain them both closed, a rock arm connected with said shaft, and a rod connected with said rock arm and extending outside the box base for operating said shaft and wing torelease either of said dampers while retaining the -other damper closed.

8. In a box base for radiators having an air inlet a damper for said air inlet pivoted at its bottom and adapted to open by gravity when release-d,.a rocking wing normally contacting with said damper to hold it closed, the'contact surface of said wing with said damperbeing curved on the arc of movement of said wing to cause a constant contact with said damper when said wing is rocked in one direction, said wing leaving said damper when rocked in the other direction to permit the latter to open, and means for rocking said wing In testimony whereof, I have hereunto set my hand in the presence of two subscribing witnesses.
